A catalytic converter is an essential component of a vehicle's exhaust system. Its primary function is to reduce harmful emissions produced by the engine, such as carbon monoxide, nitrogen oxides, and hydrocarbons. By converting these pollutants into less harmful substances, it helps improve air quality and meet environmental regulations. The catalytic converter contains precious metals like platinum, palladium, and rhodium, which act as catalysts in chemical reactions. These reactions transform toxic gases into safer emissions, such as carbon dioxide and nitrogen. Regular maintenance of the catalytic converter is important for optimal vehicle performance and compliance with emission standards.
